- "Worry wheels!"
Thomas is working late one night collecting supplies from the farm. He has been gone a long time and Percy is starting to worry. He thinks Thomas may be in trouble, but the other engines ignore him. Later that night, Thomas still has not returned and Percy asks his driver if they can go and look for him.
Percy is very nervous while he is looking for Thomas as it is very dark, but he has a lamp that lights up the way as they go. Then, Percy hears Thomas' voice calling out to him. Whilst chuffing home, Thomas had been buried and derailed in a landslide. Percy's driver attaches a rope to Thomas and Percy pulls Thomas free. Thomas is very grateful.
